Fractional Exhaled Nitric Oxide (FeNO) Result Prediction Factors in Children With Allergic Diseases

Medical University of Lodz800 enrolled

Overview

In about 800 children with allergic diseases (asthma, allergic rhinitis, atopic dermatitis) the investigators will retrospectively and cross-sectionally analyze the influence/correlation of diagnosis, treatment methods, allergy status (skin prick test results), lung function tests results on/with the concentration of nitric oxide in exhaled breath.
